Resolved System.IO.IOException: Permission denied

I don't really understand. why is this happening? why it giving this error? I updated unity to 2021.1.10 but it is the same.

it's happening when build the project for WebGL

Anybody knows a solution?

Code (CSharp):

it is exist. How can I look at its permissions?

 

I used the command and this is the result:

-rw------- 1 root wheel 6346316 2 Haz 18:55 /Applications/Unity/PlaybackEngines/WebGLSupport/BuildTools/lib/modules/WebGLSupport_AnimationModule_Dynamic.bc

 

I don't think it will work when re-install. Because this happened before version and I updated. the result is the same

 

I'll try, thanks

 

same again. Also the all platform exporting does not works because of this

 

the problem is solved. it is because of file accessing. I opened the access as root, then it is solved
